The BIGDOBRAG course is not a traveling road show….we have been doing obstacle races in Colorado for 9 years and know the MOST about mixing COLORADO MUD and designing obstacles unique to the terrain of our state.

With approximately 3 miles of muddy madness, you’ll slide down the epic 70 ft long Super Dog slide, rope climb on amazing Colorado boulders, traverse canyons on cargo nets, swing on the giant Tarzan swing, dash over our wipe out platforms and slosh your way through the 5k course with all 25 obstacles or choose our lovable 2k course with 12 of our funnest obstacles and muddiest mud pits for the whole family. The course is well marked so you can decide how much run you want in your fun once you arrive and see how everybody is feeling race day. You can even do multiple laps at no additional charge! Either way, you will create memories that will last a lifetime with friends, family, co-workers, playmates and kids of ALL ages (registration starts at age 5)

Aid / Water Stations
During the race, there will be water stations.


First wave starts at 8:30 a.m. Waves of 25 will continue every 3 minutes. You can choose the  5k and 2k course. Just follow the route signs. We will limit the number of people with proper spacing in the start area. Please arrive only (1) ONE hour prior to your wave time. Participants will be expected to abide by all parking, staging and course directions. 

For everyone’s safety, we ask faster runners to line up closer to the front of the start corral, then followed by run/walkers, walkers, and those with strollers ( if allowed ) toward the back.
